OSS-FUZZ INTEGRATIONS VIA AGENT-BASED BUILD GENERATION

blog.oss-fuzz.com13 min read

Summary from the TLDR InfoSec newsletter

OSS-Fuzz-Gen introduced an agent-based LLM approach that automatically generates build scripts and fuzzing harnesses for integrating projects into OSS-Fuzz, using iterative command execution and environment exploration to handle diverse C/C++ codebases. The system achieved 88 successful integrations from 225 tested repositories, demonstrating its ability to handle complex builds that require custom tools and dependencies. Key limitations include build scripts that avoid target source code or only support single-harness compilation, requiring post-processing validation improvements.
